DEVICE FOR FORMING WIRE BALE-TIES.

SPECIFICATION forming part of Letters Patent No. 507,642, dated October31, 1893.

Application filed January 19 1893. Serial No.- 458,967- (No model.)

T0 at whom it may concern.-

Be it known that I, ALEXANDER S. ALLEN, of Troy, Rensselaer county, NewYork, have invented a new and useful Improvement in Machines forManufacturing Wire Bale-Ties, of which the following is a specification.

In Letters Patent No. 466,563, granted to John Wool Griswold January 5,1892, there is described a form of adjustable bale tiewhich consistssubstantially in a wire band having at one end an eye formed by twistingthe wire back upon itself, within which eye is received a V-shapedsaddle of metal. In operation, the wire band is placed around the balewhen said bale is in the press, and the free end of the band is insertedthrough the saddle in the eye, and drawn tight. The running endv of theband thus becomes jammed in the angle or V of the saddle, and theexpansion of the bale, when released from the press, causes thecontraction of the eye and hence approximation of the arms of thesaddle, whereby the running end of the band becomes still more tightlyclamped and grasped.

In Letters Patent N 0. 418,456, granted December 31, 1889, to Frank B.Griswold, there is described a machine for producing, upon the end of apiece of wire, an eye by bending. over the extremity of said wire andtwisting the said parts together.

My present invention consists in an improvement in and upon the machinedescribed in said Patent No. 418,456, whereby said machine is enabled tomake the device which is set forth in said Patent No. 466,563.

In the accompanying drawings, Figures 1, 2 and 3 illustrate so much ofthe machine of Patent No. 418,456 as is modified by my invention and asis necessary for the performance thereof; it being understood that therest of the machine is substantially the same as is illustrated in saidPatent No. 418,456. Figs. 4 and 5 represent the device of Patent No.466,563, which device, as already stated, is made by the apparatusillustrated in Figs. 1, 2 and 3. In Fig. 1 is shown the position of thewire and the parts of the machine before the dog rises to bend the wireover the fixed pin. Fig. 2 shows the position of the wire and the partsof the machine after the dog has risen and bent the wire over the fixedpin. Fig. 3 shows the position of the wire and the parts of the machineafter the dog has descended upon the wire to form the eye, and after theeye so formed, which embraces the saddle, has been received and squeezedin the V-shaped notch in the projection on the under side of the dog.Fig. 4 is a front View of the Griswold bale tie and Fig. 5 is a sideview thereof.

Similar letters and figures of reference indicate like parts, and theliteral references in my present application correspond to those Whichappear in said Letters Patent No. 418,456.

38 is a rod having a longitudinal to and fro motion in the mannerdescribed in said Letters Patent No. 418,456. The end of said rod 38enters and is pivoted in a mortise in.a vertical bar, 46, upon whichbar, below the pivot, is secured the bending, dog 47. This dog has arounded downward projection at its extremity 48; and also upon said dog,on its under side, is the cam projection 49.

37 is a flat, projecting head supported upon a friction disk, 36, andcarried by a spindle, 39, to which, by suitable gearing, anintermittent, rotary motion is imparted by mechanism which is not hereshown, but which is fully described in Letters Patent No. 418,456,hereinbefore referred to. Bolted to the plate 37 is a fixedoam, 50. Whenthe parts are in the position shown in Fig. 1, the dog 47 rests uponsaid cam 50, and is retained between the plate 37 and a similar plate,51, outside of said cam. In the upper front portion of the dog 47 thereis a longitudinal score (not shown), on opposite sides of which projectupward pins, one of which is shown at 52. Supported upon the upperportion of the bar 46 is a downwardly-bent plate, 53, which is slottedand secured by a set-screw, 54, passing through the slot so that thevertical portion of said bar maybe adjusted nearer to or farther fromthe extremity of the bending dog 47. Projecting from the l1ead'37 is aforming-pin, 57.

The aforesaid parts operate in the manner set forth in Patent N 0.418,456 as follows, and constitute a device for bending back upon itselfthe end of the wire A upon which the eye is to be formed. The wire Abeing introduced under the forming-pin 57, passes between the pins 52 onthe dog 47 until its end reaches the stop 53. The wire then lies in thegroove on the upper side of the dog 47, and the distance to which itextends over the dog is limited by the position of the stop 53, which isadjusted in the manner already described. By the mechanism set forth inPatent No. 8,456, the rod 38 is caused to move toward the left of thedrawings. As it so moves, the cam 49 on the under side of the dog 47meets the incline of the fixed cam 50,

supported on the head 37, and rises over said cam. As it rises, itcarries up with it the end a of the wire which is beyond the forming-pin57; sothatthis end of the wire assumesfirst a vertical positionand thenis bentbackzowvard overthe pin .57, the end 48 of the dog ifinallyriding overthe loop and the parts as suming-the position asshown; in Fig. 2. *In order now to form the eye, the rod 38 conitinuesto move outward, andthe lower end thebar46 meets an adjustable stop, 58,on

the side of the fixed cam 50; and aS 'LhG bar 46 continues to be pressedagainst this it stop, the extremity, 4.8, of the dog is forced clownwardso as to bring-the bent-overpart of the 0 wire into proximity to thestanding part, as shown in Fig. 3. 1 will now describe how theparts,operat- .ing in the manner before described, manufaci ture the bale tierepresented in :Figs. 4 and 5. 5 t The said tie consists of-an eye, B,formed on the end of the band, which eye B receives a V-shaped saddle,C, which is preferably made i i of wrought metal. Onthe outside of thesaddle formed by bending the edgesthereof to- 40 gether is a groove, D,in which groovethe wire ofthe eye B lies. It will be seenthat I havechanged the shape of the forming-pin 57 from a 2 that which is shown inPatent No.418,456, to a pin of triangular cross-section which is adaptedto receive upon it the saddle O. This saddle is placed in position uponthe pin 57 i by hand before the wire A is introduced into i the machine,as shown in Fig. 1.

i It will be evident from Fig. 2that the operation ofvthe dog 47 is,while bending the .wire A around the pin 57, likewise to carry a saidwire snugly into the groove of the sad- ..tdle C. It is,however,necessary that thesad- -dle should be forced down tightly against the iwire at the end of the eye; for I have found, t by actual experimentwith these baleties, i that when such is not the case, the saddle isliable to become rupturedunder heavy strain;

this beingdue to the fact that it isnotprop 6o erlysupported orbacked bythe wire. I therefore provide, on theunder side of thedog 47,

aprojection, E, in which projection there is a V-shaped recess, F. Thisrecess is so constructed and disposed that when the parts 6 5 reach theposition shown in Fig. 3, the pin57 the saddle O thereon and the wire A(now bent over said saddle) will all be received in said recess F, andthe remaining additional forward movement of the rod 38 causes the wireA and saddle C to be closely jammed or pressed together between the pin57 and the sides of the recess F. In this way the wire is closely andsnugly forced into the groove D on the saddle C; and also in the manneralready described, the end 48 of the dog presses the wire in rear of thefastening pin downward so as to form the eye, as indicated in Fig. 8.

The remaining operation of the machine to effect the twisting of the eyeis exactly the same as is described in said Patent No. 418,45 6, andtherefore needs no further description.

I claim 1. The combination: in amaehinefor the manufactureofbaletiefastenings of thertype hereinbeforedescribed, of a fixedsupportconstructed to receive the thimble orwsaddle of the eye, meansfor bending the'wire around said saddle,and means for twisting theapproximated parts of the wire togethertoform said eye, substantially asdescribed.

2.The combination in a machine for the manufacture of baletie fasteningsof thetype hereinbefore described, of a fixed supportconstructed toreceive the thimble or saddle of hereinbefore described, of a fixedV-shaped pin or support 57 adapted toreceivethesaddle O, mechanism forbending the wireA around said support to forum an eye B,anda=reciproeating block E havinga V-shaped opening F adapted to receivesaid supporthntermittently movingvupon the same and thereby compressingthe wire of eye B into the-groove D of the saddle 0,,substantially asdescribed.

4. The combination in a wire-bending machine, of a fixed pin ofwedge-shaped crosssection 'aroundwhich-the wireis bent,a:dog swinging ina vertical plane and also: having atitscenter of oscillation areciprocating motion toward and from said pin, a projection on onesideof said dog having a wedge 01' V-shaped recess turned toward andadapted to receive said pimand a fixedcam :placed beneath: said dogandn'egulating its upper throw; the aforesaid parts beingarranged andoperating so that when a wire is i ntroducedunder said pin and over saiddog, the

"forward motion of said dog" over saidcam shall cause said dog to riseand to carry and bend said wire over said pin, and the continuingforward movement of said dog shall cause the recess in said projectionto receive: the

said wire 100p and compress the same upon F adapted to receive said pin57, substansaid pin. tially as described.

5. The combination of the rotary head 37 and the wedge or V-shapedforming-pin 57 ALEXANDER ALLEN 5 and fixed cam 50 thereon, the movablerod 38 Witnesses:

and dog 47 pivoted thereto, and on said dog FRANK B. GRISWOLD, theprojection E having the V-shaped recess W. W. RoUssEAU.
